I want to read the DROM chip with my programmer, but I can't ID the chip. Does anyone know what kind it is? It is in a PLCC32 package and the label on it is:
I am sure at least some of that is DEC stuff, unrelated to the type of chip. However, none of those parts of the label seem to correspond to any EPROM I can find. My programmer's software has an auto detect feature, but that also failed to ID the chip. I don't really want to remove the label if I can avoid it.
The underside is marked
522 (might be 322)
None of these appear to match anything either.
Any ideas what it might be?
